Abstract

Patente de Invenção: SINCRONIZAçãO DOS NìVEIS DE POTêNCIA DE LIGAçãO ENVIADA DE ESTAçãO BASE DURANTE REPASSE ENTRE SETORES DE ESTAçãO BASE EM UM SISTEMA DE RADIO COMUNICAçãO MóVEL Um método e equipamento para controlar os níveis de potência de transmissão de primeiro e segundo transreceptores de estação base, em que os primeiro e segundo transceptores de estação base estão respectivamente associados com os primeiro e segundo setores de uma célula. é inicialmente determinada a força do sinal recebido de um sinal de comunicação que chega na estação móvel. Um valor de controle de potência que está baseado na força do sinal recebido é a seguir transmitido a partir da estação móvel par os primeiro e segundo transceptores de estação base. Um primeiro valor de controle de potência recebido é a seguir gerado pela tentativa de receber o valor de controle de potência transmitido no primeiro transreceptor de estação base e um segundo valor de controle de potência recebido é gerado pela tentativa de receber o valor de controle de potência transmitido no segundo transreceptores de estação base. um valor em comum de potência de transmissão é calculado em um controlador de estação base para os primeiro e segundo transreceptores de estação base quando os primeiro e segundo valores de controle de potência recebidos são desiguais. O sinal de comunicação é a seguir transmitido a partir dos primeiro e segundo transreceptores de estação base de acordo com o valor em comum de potência de transmissão.Invention Patent: SYNCHRONIZATION OF BASE STATION CONNECTION POWER LEVELS DURING BETWEEN BASE STATION SECTORS IN A MOBILE COMMUNICATION RADIO SYSTEM A method and equipment for controlling the transmission power levels of the first and second base stations. wherein the first and second base station transceivers are respectively associated with the first and second sectors of a cell. the strength of the signal received from a communication signal arriving at the mobile station is initially determined. A power control value that is based on the strength of the received signal is then transmitted from the mobile station to the first and second base station transceivers. A first received power control value is then generated by attempting to receive the power control value transmitted on the first base station transceiver and a second received power control value is generated by attempting to receive the power control value. transmitted on the second base station transceivers. a common transmit power value is calculated on a base station controller for the first and second base station transceivers when the first and second received power control values are uneven. The communication signal is then transmitted from the first and second base station transceivers according to the common transmission power value.
